Under the matchmaking of the three major groups of Ice Axis, Luo Axis and Complex Axis, Xingcheng Special Steel and Northeast Special Steel soon sent representatives to the capital to meet with Chang Haonan.

After a simple greeting, Chang Haonan got straight to the point:

"Two, our torch company has developed a set of design methods for chemical heat treatment process, but metallurgy is a heavy asset project after all, with a long return on investment, and our company's expected business scope does not include this industry, so I hope to transfer this method to solve the problem of high-end bearing steel materials that we urgently need at present."

The reason why it is said to be a "method" is because this research is still in a fairly early stage, and in addition to Chang Haonan himself, there are only a few researchers from the Institute of Computing Technology of the Academy of Sciences who are in charge, so that a complete software has not yet been formed.

After saying this, the expressions and eyes of the two people on the other side made Chang Haonan feel that if it weren't for the three bearing groups as intermediaries, plus the endorsement of various official names, he would probably be regarded as a charlatan.

"Mr. Chang, this ......"

Fang Manchang, the chief craftsman from Xingcheng Special Steel, hesitated to open his mouth, but there were so many slots that he didn't know where to start asking for a while.

Metallurgy is a bit like the herbalism or alchemy of some fantasy works, at least in the late '90s.

Despite a superficial knowledge of the role of the individual elements in the composition of an alloy and the effects of various material treatment processes on performance, the development of new formulations in general is still highly dependent on experience, luck and the skill of the alchemist, that is, the metallurgical engineer.

After the birth of atomic absorption spectrometers and flame atomizers, the specific composition of materials has completely disappeared from secrecy, as long as you can get a sample, you can find an undergraduate student to spend days or even hours to analyze it.

However, even with the exact same elemental formulation, different processes can bring very different material properties.

In the field of chemical heat treatment mentioned by Chang Haonan alone, the commonly used means can be divided into carburizing, nitriding, carbonitriding, nitrocarburizing, composite diffusion, and fine surface diffusion from the general surface......

If it is based on the state of the infiltration agent in the furnace or the ion generation pathway, there are other ways to classify it.

Each technology also includes a few tens or hundreds of process parameters, resulting in an almost infinite number of possibilities.

This is the secret of each technology-leading country or enterprise.

For example, anyone, as long as you find a random process manual, you can find that the national standard number of M50 steel is 8Cr4Mo4V, and the national standard number of M50NiL steel is G13Cr4Mo4Ni4V, but this does not mean that anyone can smelt the latter.

In other words, it cannot be completely smelted up to standard.

After M50NiL steel was first developed by SKF in Sweden, many capable peers also quickly followed up with relevant research, and although the steel produced in different countries can finally be said to be M50NiL, there are still differences in specific properties.

For example, the steel produced in Germany, Japan, the United States, the Soviet Union (Russia) and other countries, although it is not exactly the same as the original goods in Sweden, but in general, it has its own strengths, or at least the gap is not large, and it can be completely substituted for each other in use.

However, the M50NiL steel produced in countries with relatively weak technology is far behind the original product in one or more aspects, and even some of the properties are worse than the M50 before treatment.

Unfortunately, Huaxia is in the latter category.

In the previous life, it was not until the second half of the 2010s that the bearing steel used in the domestic third-generation engine was completely replaced by imports.

And now, someone said that he had the ability to "design" a set of heat treatment process, and the first reaction of the two insiders who were responsible for the process was not to believe it.

However, before Fang Manchang could organize the next language, his question was interrupted by Guo Zhanwen, who came from Northeast Special Steel next to him:

"I don't know if it's inconvenient for Mr. Chang to introduce your design method...... Principle? ”

Fang Manchang, who was only halfway through the words, glanced at the latter with slightly strange eyes.

That's a strange question.

For them as a profession, there is a distance between understanding the fundamentals and industrial practices, and even if they say it, it doesn't mean anything.

"It's pretty simple."

Chang Haonan didn't care too much, and directly explained:

"The driving force of chemical heat treatment is the chemical niche gradient, at a certain temperature, heat preservation for a period of time, the diffusion elements are first enriched on the surface, when the diffusion concentration reaches a certain value, it will begin to diffuse from the surface centripetal part, the outermost layer is the permeability layer, then the diffusion layer, and finally the matrix, the whole heat treatment process can be roughly divided into three stages: chemical permeability decomposition, adsorption and diffusion."

"In the whole three steps, according to the chemical reaction, thermodynamics, and Fick's diffusion law, the prediction and control model of the carbon concentration distribution in the permeate layer can be established, and the process design and optimization can be realized."

"That's it...... That's it? ”

Fang Manchang was still waiting to continue listening, but Chang Haonan stopped when he said this.

"Of course, that's not all...... In fact, I expect that the most complete and accurate method should be to directly carry out the molecule, which is actually the simulation at the atomic level for metals, and calculate the influence of different treatment processes on the properties of metal materials directly from the perspective of microscopic particles, but with the current computer level, it is still far from being possible, so I just doped some molecular simulation ideas into it to make the whole chemical heat treatment process model more reasonable. ”

"As for the specific technology...... Of course, that's our trade secret, and if I was willing to share it for free, we wouldn't have had this meeting today, wouldn't we......"

"Oh...... Also to Ha ......"

Fang Manchang, who was scolded back, showed a somewhat embarrassed expression.

Although Chang Haonan's previous principle is the Tao, for an industry insider like him, it is still not convincing enough.

But what people said later also makes sense -

If I explain everything to you, what kind of business is there to do?

But just when he hesitated, Guo Zhanwen on the side had already skipped the middle step directly:

"It is worthy of Mr. Chang, we have already heard of your ability and the level of your company, so what is next...... When can we sign the contract? ”

"Huh?"

"Huh?"

Not to mention Fang Manchang, even Chang Haonan didn't expect the plot to go in such a direction.

He even prepared a few examples related to M50 steel in advance to enhance his persuasiveness, but now it seems to be ......

Not at all?

Is trust between people so easy to achieve?

And you must know that Chang Haonan's asking price for this technology is 7.5 million yuan, as far as a technology that is not even a semi-finished product is concerned, although it is not black-hearted, it is not cheap.

His minimum psychological expectation was about 5 million, but he thought that there should be a bargaining process, so he must have quoted higher first.

It didn't work either.

As for Fang Manchang next to him, he was even more dumbfounded.

The special steel industry is not big, there are basically no secrets in the industry, and the level of domestic special steel is not very good, and the competition within the industry is more than when they are warmed together, so they basically know each other's situation.

Northeast Special Steel is formed by the merger of the original Dalian, Fushun and Beiman three special steels, the scale is much larger than Xingcheng Special Steel, and the turnover is also higher, but the profit situation is not optimistic, among which Dalian Special Steel has just been pulled back from the brink of bankruptcy not long ago, far from being able to casually take out a huge amount of money.

Taking advantage of the break between meetings, Fang Manchang hurriedly excused himself to go to the toilet and pulled Guo Zhanwen to a secluded and uninhabited corner.

"You're going to take this money like this?"

The two were college classmates before, and although they entered different companies, they have always kept in touch and have a good relationship.

"This is what our company means, no matter what, this money will definitely be given."

Guo Zhanwen lit a cigarette for himself and the other party:

"This is also for the sake of our two old classmates, I'll give you a pang."

"At the end of last year, the country suddenly began to engage in a Seiko plan, this Chang Zong was the general consultant of the entire plan, and our three steel mills also took this opportunity to apply for the completion of the reorganization and merger, which is now Northeast Special Steel."

This story is known to the industry, so Fang Manchang took a deep puff of cigarette, nodded, and motioned for the other party to continue.

"Two months ago, the state started to work on the 973 plan again, although I didn't see his name in the expert advisory group, but guess what? I saw him again among the members of the Advisory Group of Experts on Important Scientific Frontiers. ”

"And that kind of thing?"

At this time, Fang Manchang also realized the seriousness of the matter.

Although Xingcheng Special Steel also has a state-owned background, it is not a state-owned enterprise in the full sense of the word, and the news in all aspects is still not so well-informed.

Guo Zhanwen concluded:

"This Chang Zong, we don't care if he is able to break the sky or the relationship is broken, in short, he can talk on both sides of the Science and Technology Commission and the Science and Technology Commission, and now the two frontier research projects are still related to him, at this juncture, the company he manages wants to sell a set of process design methods to us, do you dare not buy it?"

"I ......"

Obviously, Fang Manchang knew that what his old classmate said made sense.

But he didn't get that much authority before he came:

"I'll have to contact the company to decide...... 7.5 million, which is equivalent to our profit in half a year last year, and we have to wait until the afternoon ...... at the earliest."

"I can't wait for you, the company asks me not to show any hesitation, I advise you to act quickly......"

Guo Zhanwen shook his head, threw the cigarette butt into the sink next to him, turned around and walked back in the direction of the conference room.

Fang Manchang, who was looking at his back, gritted his teeth and trotted all the way to a public phone outside......
